Hi @Lynn1810 , oddly I was told just the opposite about alloying for a LLC. I will reach out my attorney.
You do not need to put in LLC in your listing.
not sure of the why your guests need to know either?
I owned a resturant/pub in Illinois & it was not on the name, not on my signature and as I pretty sure know one knew if I was a Llc, S-Crop etc. Only Illinois Revenue & Uncle Sam needed to know.
I would find it interesting to see the other comments, especially if an attorney ran an AirBnB
great question!
